Explore our engineering-grade heavy road machinery, built for heavy-duty pavement milling, cold recycling, and aggregate processing.
Strategic shift toward sustainable asphalt pavement rehabilitation, life-cycle cost reduction, and high-efficiency material reclamation.
The global infrastructure sector is undergoing a monumental transformation. The era of unchecked highway expansion is giving way to intensive pavement asset management, preventive maintenance, and sustainable pavement rehabilitation. Within this macroeconomic matrix, the cold road surface milling machine (cold planer) stands as the indispensable foundation of modern highway engineering.
A road surface milling machine is engineered to remove distressed asphalt layers, rutting, surface cracks, and structural deformities with sub-millimeter precision. By restoring macro-texture and grade elevation, milling machines create a clean, mechanical keyway for fresh asphalt overlay while yielding high-value Reclaimed Asphalt Pavement (RAP).
Information Gain Insight: According to global transport research, cold milling combined with Reclaimed Asphalt Pavement (RAP) recycling reduces raw aggregate consumption by up to 60% and cuts bitumen expenditure by up to 35%, making it the single most capital-efficient process in pavement maintenance.
Fusing academic engineering research with industrial manufacturing excellence since 1998.
HEM Group (HME TOP Machinery Equipment Co., Ltd.) was founded in 1998 by a distinguished coalition of professors from Chang'an University—China's premier academic institution for highway engineering, mechanical dynamics, and transport infrastructure. Originally established as Xi'an Hongda Communications Technology Co., Ltd., the enterprise was established as the nation's earliest pioneer in independent research and design of road construction machinery.
Over more than a quarter-century of focused engineering, HEM Group has translated academic breakthroughs in mechanical dynamics, engine-hydraulic power matching, closed-loop hydraulic drive technology, and digital electronic leveling control into heavy-duty road machinery manufactured for severe field environments.
Analyzing cutter drum dynamics, hydraulic power transmission, and electronic leveling systems.
The milling drum is the heart of the cold planer. China's top manufacturers deploy heat-treated alloy steel drums equipped with quick-change toolholder systems (such as HT22/HT11 toolholders).
Engine power curves must continuously adapt to shifting asphalt densities and variable milling depths to prevent engine stall and maintain high fuel efficiency.
Achieving flawless transverse slopes and longitudinal profiles requires integrated automatic levelling sensors.
Harmonizing road milling machines with paving, recycling, and earthmoving machinery for complete project execution.
A road milling machine does not work in isolation. Modern highway projects demand a tightly coordinated suite of specialized machinery to complete milling, binder spraying, paving, and crushing cycles rapidly.
High-capacity Road Surface Milling Machines strip damaged asphalt courses, transferring RAP onto trucks via folding conveyor systems.
In-situ structural reclamation performed by Cold In-Place Recyclers (CIPR) and precision Cement Spreaders, reusing 100% of existing roadbed materials.
Precision binder distribution via Intelligent Bitumen Distributors and Synchronized Chip Sealers, followed by Asphalt Pavers and Road Rollers.
We supply heavy earthmoving equipment including wheel loaders, excavators, backhoe loaders, and graders. Used worldwide in bridge construction, seaports, industrial parks, and community road development.
Complete paving suites including asphalt mixing plants, asphalt pavers, road milling machines, paver feeders, slurry seal machines, and vacuum road sweepers built for durable road construction.
Mobile primary vibrating screens, mobile jaw crushers, and roller crushers engineered to crush milled RAP or virgin aggregate directly inside quarry and mining sites.
Engineered to perform across extreme climate zones, complex urban terrain, and heavy industrial load corridors.
In regions across Southeast Asia, West Africa, and Latin America, high ambient temperatures (exceeding 45°C) accelerate asphalt soft-deformation while placing immense strain on engine cooling systems.
Metropolitan maintenance demands compact milling machines capable of maneuvering around manholes, tight turn radii, and urban street furniture with minimal acoustic disruption.
Pioneering autonomous milling guidance, telematics analytics, and zero-emission hybrid drivetrains.
Real-time acoustic and thermal sensing embedded within toolholders to detect tooth breakage instantly and predict pick replacement intervals.
RTK-GNSS positioning paired with LiDAR scanning enables fully autonomous line-following and automated cut-depth adjustment.
Transitioning auxiliary functions and conveyor drives to electric motors, cutting fuel consumption by up to 25% on long-haul highway projects.
Cloud connected IoT modules transmit real-time fuel usage, total m² milled, engine load percentage, and maintenance alerts directly to fleet managers.
Unmatched OEM capability, global service hubs, and academic technical support.
Decades of academic R&D and industrial manufacturing experience directly focused on high-end road construction and maintenance machinery.
Expert guidance covering structural mix design, bitumen emulsion ratios, aggregate grading, and specialized rehabilitation techniques.
Tailor-made equipment configurations designed for specific climate conditions, high-altitude mining sites, or custom drum widths.
Round-the-clock technical feedback, remote diagnostics, and expert engineers available for rapid overseas site training.
Dedicated regional teams and spare parts warehousing in Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka. Exported to over 60 countries including India, Nigeria, Eritrea, Mozambique, Congo, Australia, Fiji, Bolivia, and beyond.
Detailed technical answers addressing buyer inquiries, milling specifications, maintenance, and logistics.
Our cold road surface milling machines cover drum widths ranging from compact 500mm utility planers up to high-capacity 2,000mm (2-meter) highway milling machines. Cutting depths are continuously adjustable from 0 to 330mm in a single pass, supported by automated electronic level sensors.
Our design integrates heavy-duty hydraulic anti-vibration damping systems engineered by Chang'an University researchers. The Electronic Control Unit dynamically alters hydrostatic travel speed when high mechanical torque resistance is encountered at the milling drum, maintaining constant engine RPM and preventing engine stalls.
Yes. The uniform particle gradation produced by our precision pick layout allows RAP to be immediately processed by our Cold In-Place Recyclers (CIPR) or transported to an asphalt mixing plant to replace virgin aggregate and bitumen, lowering material costs significantly.
We maintain active service teams, technical centers, and local spare parts warehouses in Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka. We offer 24/7 online technical support, fast-wear part dispatches, and on-site commissioning by field engineers.
